GeForce 8800 GT 256MB 44800 MB/sec
GeForce GT 440 1.5GB 43200 MB/sec
Difference: 1600 (4%)

Texel Rate

The GeForce 8800 GT 256MB will be much (approximately 136%) better at texture filtering than the GeForce GT 440 1.5GB. (explain)

GeForce 8800 GT 256MB 33600 Mtexels/sec
GeForce GT 440 1.5GB 14256 Mtexels/sec
Difference: 19344 (136%)

Pixel Rate

The GeForce GT 440 1.5GB should be quite a bit (about 49%) better at full screen anti-aliasing than the GeForce 8800 GT 256MB, and should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GT 440 1.5GB 14256 Mpixels/sec
GeForce 8800 GT 256MB 9600 Mpixels/sec
Difference: 4656 (49%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
